Discussion

The amount of pollen in the air for Tuesday will be falling in the moderate range. This lowering of pollen concentrations is a result of rising humidity and expected precipitation in the morning, afternoon and evening which tends to wash pollen out of the air. With this amount of reduction in pollen levels, tomorrow should be better for allergy sufferers.
